There's a substantial lag, though, between finding out how infectious a variant is and how deadly it is (AIUI the rough averages are 2 weeks from infection to hospitalization and another 2 weeks from hospitalization to deaths, but that might have changed). That means that the data on how infectious a variant is becomes available ~1month ahead of information about how dangerous it is. Have we even had confirmed spread of these variants for a month?
